Nina Dobrev is willing to go naked for a cause close to her heart. In this case, that cause is Obamacare.

The Affordable Care Act, which caused Republicans to shutdown the government on Oct. 1, is something "The Vampire Diaries" star is a big supporter of. She stood topless on Instagram to encourage her followers without healthcare to get some.

"Im Canadian. We have healthcare for all. If you dont have insurance go to [HealthCare.gov] and#GetCovered ,Because w/o it, youre naked," she posts to Instagram.
